Ubuntu 20.04 prod list does not include aziot-edge

Question

Trying to setup aziot-edge on a Ubuntu 20.04 VM with this:

*curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list > microsoft-prod.list
sudo cp ./microsoft-prod.list /etc/apt/sources.list.d/
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
sudo cp ./microsoft.gpg /etc/apt/trusted.gpg.d/
sudo apt-get update
sudo apt-get install moby-engine
sudo apt-get install aziot-edge*

Last command fails with:

*admin@ubuntu1804lts:~$ sudo apt-get install aziot-edge
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package aziot-edge is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'aziot-edge' has no installation candidate*

Ran the same with 18.04 and it installs fine but with the following errors:

*admin@ubuntu1804lts:~$ sudo iotedge system status

I'm assuming the errors with 18.04 are due to a version mismatch. Is this correct?
If yes, do I keep running the 18.04 version? If so, how do I resolve these errors?

If not, what is the correct prod list/package list source to install 20.04 versions for moby and iotedge?

Answer 1

Hi @SB ,

Are you following this tutorial?: Create and provision an IoT Edge device on Linux using symmetric keys

Ran the same with 18.04 and it installs fine but with the following errors:

If you complete that tutorial till the end, do you still see those errors when sudo iotedge system status ?

Ubuntu 20.04 prod list does not include aziot-edge

As mentioned in Azure IoT Edge supported systems "The Ubuntu Server 18.04 installation steps in Install or uninstall Azure IoT Edge for Linux should work without any changes on Ubuntu 20.04."

Therefore let me further investigate this.

Thanks!
